Honestly, both are great foods! The companies run feeding trials and employ veterinary nutritionists on staff to make sure the food is balanced correctly. I personally feed my own dogs Iams, but you could feed Chloe either. Best of luck.

    Royal Canin is one of my top choices! It meets AAFCO standards, runs their own feeding trials, and have veterinary nutritionists on staff. It's one of only four brands that have all this, the others are Hill's Science Diet, Purina ProPlan, and Iams. I feed my dogs Iams. I think you have Chloe on an excellent food and I would not change it! Keep up the good work :-)
